How long you have had Bartlets for? Do they fight?Skip the blue tang as they get too big and active for a 100 gallon, get a dwarf angel instead. My 5' 100 gallon has the following in it (and I still have a few more additions still planned but not purchased yet).
1 Skunk Tilefish (Hoplolatilus marcosi)
1 Razor Goby (Oxymetopon cyanoctenosum)
1 Exquisite Firefish (Nemateleotris exquisita)
1 Pink Headed Fairy Wrasse (Cirrhilabrus chaliasi)
1 Yellow Flank Fairy Wrasse (Cirrhilabrus ryukyuensis)
1 Whipfin Fairy Wrasse (Cirrhilabrus filamentosus)
1 Indo Lubbock's Fairy Wrasse (Cirrhilabrus lubbocki)
1 Katoi Fairy Wrasse (Cirrhilabrus katoi)
1 Torpedo Wrasse (Pseudocoris yamashiroi)
1 Yellow Banded Possum Wrasse (Wetmorella nigropinnata)
1 Yellow Coris Wrasse (Halichoeres chrysus)
1 Dusky Wrasse (Halichoeres marginatus)
1 Cosmetus Wrasse (Halichoeres cosmetus)
1 Neon Wrasse (Halichoeres garnoti)
2 Banggai Cardinalfish (Pterapogon kauderni)
1 Pajama Cardinalfish (Sphaeramia nematoptera)
1 Fusilier Damsel (Lepidozygus tapeinosoma)
3 Green Chromis (Chromis viridis)
5 Bartlett's Anthias (Pseudanthias bartlettorum)

1 Lantern Basslet (Serranus baldwini)
3 Black Molly (Poecilia sphenops)
1 Pacific Double Saddle Butterflyfish (Chaetodon ulietensis)
1 Latticed Butterflyfish (Chaetodon rafflesi)
1 Rhino Bannerfish (Heniochus varius)
1 Flame Angelfish (Centropyge loricula)
1 Yellowfin Angelfish (Centropyge flavipectoralis) - in quarantine
1 Flagfin Angelfish (Apolemichthys trimaculatus) - in quarantine
Still going to hopefully add a coral beauty angel, a few more green chromis and fusilier damsels, a pair of clowns, some type of shrimp goby, a Bali tiger jawfish or 2, another 3 butterflies, a regal angel, and a cleaner wrasse. Possibly a couple more wrasses as well. I tend to stock much heavier than most people though.
How many times do you feed them?
